<a name="bnckq"></a><h3>JAX-WS Coffee Supplier Service</h3>
<a name="indexterm-3131"></a><a name="indexterm-3132"></a><a name="indexterm-3133"></a><p>The Coffee Break servers are clients of the JAX-WS coffee supplier service. The
service code consists of the service implementation class, and several JavaBeans components that
are used for method parameters and return types. The JavaBeans components are:</p>
<ul><li><p><tt>AddressBean</tt>: shipping information for customer</p></li>
<li><p><tt>ConfirmationBean</tt>: order ID and ship date</p></li>
<li><p><tt>CustomerBean</tt>: customer contact information</p></li>
<li><p><tt>LineItemBean</tt>: order item</p></li>
<li><p><tt>OrderBean</tt>: order ID, customer, address, list of line items, total price</p></li>
<li><p><tt>PriceItemBean</tt>: price list entry (coffee name and wholesale price)</p></li>
<li><p><tt>PriceListBean</tt>: price list</p></li></ul>
<p>These JavaBeans components are propagated to the clients by means of the <tt>wsimport</tt>
tool.</p>

<a name="bnckr"></a><h4>Service Implementation</h4>
<p>The <tt>Supplier</tt> class implements the <tt>placeOrder</tt> and <tt>getPriceList</tt> methods. So that you
can focus on the code related to JAX-WS, these methods are short and
simplistic. In a real world application, these methods would access databases and would
interact with other services, such as shipping, accounting, and inventory.</p><p>The <tt>placeOrder</tt> method accepts as input a coffee order and returns a confirmation
for the order. To keep things simple, the <tt>placeOrder</tt> method confirms every
order and sets the ship date in the confirmation to the next day.
The source code for the <tt>placeOrder</tt> method follows:</p><pre>public ConfirmationBean placeOrder(OrderBean order) {

    Date tomorrow = DateHelper.addDays(new Date(), 1);
    ConfirmationBean confirmation =
        new ConfirmationBean(order.getId(), DateHelper.dateToCalendar(tomorrow));
    return confirmation;
}</pre><p>The <tt>getPriceList</tt> method returns a <tt>PriceListBean</tt> object, which lists the name and
price of each type of coffee that can be ordered from this service.
The <tt>getPriceList</tt> method creates the <tt>PriceListBean</tt> object by invoking a private method named <tt>loadPrices</tt>.
In a production application, the <tt>loadPrices</tt> method would fetch the prices from
a database. However, our <tt>loadPrices</tt> method takes a shortcut by getting the prices from
the <tt>SupplierPrices.properties</tt> file. Here are the <tt>getPriceList</tt> and <tt>loadPrices</tt> methods:</p><pre>public PriceListBean getPriceList() {

    PriceListBean priceList = loadPrices();
    return priceList;
}

private PriceListBean loadPrices() {

    String propsName = "com.sun.cb.ws.server.SupplierPrices";
    Date today = new Date();
    Date endDate = DateHelper.addDays(today, 30);

    PriceItemBean[] priceItems = PriceLoader.loadItems(propsName);
    PriceListBean priceList =
        new PriceListBean(DateHelper.dateToCalendar(today),
            DateHelper.dateToCalendar(endDate), priceItems);

    return priceList;
}</pre>
